# Getting Started with Qt

You can install the Qt Framework and tools by using an online or offline installer or by building the source packages yourself. In the online installer, you can select the Qt versions, tools, and Add-On components to download and install depending on the license attached to your Qt Account.

An offline installer is a single package that contains all of Qt and Add-Ons relevant for a target platform.

You can download Qt 5 installers from the Downloads page.

You can use the Qt installers to download and install the following components:

- Qt libraries, prebuilt for a particular development platform (operating system and compiler)
- Qt Creator integrated development environment (IDE)
- Reference Documentation and examples
- Qt in source code form (needed only if you want to build the framework and tools yourself)
- Add-On components that are relevant for different platforms

After downloading, start the installer like any executable on the development platform.

To run the installer, you need a Qt Account. You can use your Qt Account credentials to sign-in to all Qt services, including the forums and wiki. If you do not already have a Qt Account, you can create one during the installation process.

To complete the installation, select the components that you want to install and follow the instructions of the installation program.

Use the Maintenance Tool under <install_dir> to add components and to update or remove installed components.
